The implicit promise of heap_alloc_caps() and friends is that the memory it returns is fit for the purpose as requested in the caps field. Before this commit, that did not happen; e.g. DMA-capable memory wass returned from a correct region, but not aligned/sized to something the DMA subsystem can handle. This commit adds an API to the esp_mm component that is then used by the heap component to adjust allocation alignment, caps and size dependent on the hardware requirement of the requested allocation caps.
